This book is aimed at the serious student of the French language at an intermediate / advanced level who really wants to improve their spoken and written French language skills. As I attend a weekly Advanced French conversation group and also visit France regularly I already have a number of books on French grammar and translation, therefore I did hesitate slightly before buying this huge tome. However I have absolutely no regrets about my purchase and would recommend this to anyone seriously seeking the most appropriate 'Bon Mot' for French conversation. This dictionary is surprisingly easy to use. The words themselves are printed in blue which means that they stand out on the page which speeds up the hunt significantly. This dictionary contains much more than just straightforward French / English translations; there are useful colloquialisms, idioms and sayings, conjugation guidelines and hints and tips for writing formal and informal letters and, for some words and phrases, even a guide as to whether they are acceptable in polite society! A bit heavy to carry around - but I believe there is also a very good pocket version!
